Wait, _I_ have an objection to exporting this symbol.

I really don't think it is needed at this point in time, as we really
need to figure out exactly what your driver is doing to want to need to
call this function.

So please, let's not export it for now, when we get to the point that we
all agree that this driver is doing the "correct" thing, then we can
export the symbol, ok?
